COMBINATION COOKING-STOVE AND HEATER.

which, without complications in its structure, without adding materially to the cost of manufacture and without additional consumption'offuel, will fully meet the usual requirements of a cooking stove, and Will act as a hot airfurnace and effectually heat one or more additionalrooms.

With this object in view, Lhave devised the novel cooking stove and heater which I willn'dw describe referring to the accompanying drawing formmg a part of this specification and using reference characters to'indicate the several parts.

Figure 1 is a perspective view, partly broken away, illustrating the construction and mode of operation of my novel stove, and

Fig. 2 is a horizontal section, looking down.

' with a draft chamber 14.

The essential feature of noveltyis an air heating chamber 15, which'sirrounds the fire box on four sides, lying outside the fire brick and the Water front. The heating chamber is supplied with air by means of a pipe 16 which passes through the draft chamber under the oven, and is provided with an external opening 17 at the end of the stove opposite to the fire box. Opening 17 is provided with a damper 18 by which the supply of air to the heating chamber may be regulated .or wholly cut ofi as required. By causing the air supply pipe to pass through the draft chamber, the air in said pipe is preheated before it reaches the heating chamber. While in the heating Specification of Letters Patent.

chamber, the circulation of the air is entirely f1. e on all four sides'of the chamber. As the air is preheated before it reaches the chamber, it will necessarily rise therein and will pass out by means of a hot air pipe 19, leading from the top of the chamber and provided with a damper 20, by which the volume of air passing from the heating chamber is controlled or is entirely out off, as may be required. Supply pipe 16 is shown as leading into the heating chamber near one corner thereof, and the hot air pipe as leading therefrom at the corner diagonally opposite. I have shown but a single air supply pipe 16 and a single hot air pipe 19, but a plurality of supply pipes and a and plurality of hot air pipes, either or both, may be used if preferred, these and otherobvious details of construction being wholly within the scope of the invention. Where a plurality of rooms are to be heated, individual hot air pipes may lead to the several rooms or branch air pipes may lead from hot air pipe 19. Q1 .and 22 denote the usual cold and hot water pipes leading to and from the water front.

The operation of the invention is so simpie as not toirequire description. In factit is self operating. So long as neither damper 18 or 20 is wholly closed, air will pass through the supply pipe, will be preheated therein, and pass to the heating chamber, and will be further heated in the chamber and pass by means of the hot air pipe to the room or rooms to be heated.

Having thus described my invention, I claim:

A stove of the character described (mmprising a stove body provided with a fire box, an oven, a draft chamber under the oven, and a heating chamber surrounding the ire box and isolated from said draft chamber, an air inlet pipe passed through the draft chamber and leading direct to the lower portion of the heating chamber at one side of the stove, and a hot air delivery 'pipe leadmgfrom'the heating chamber near the top thereof and at the other side of the stove, whereby the incoming air is caused 'to divide and pass on both sidesof the fire box while traveling through the heating chamber. I

In testimony whereof I affix my signature.
